Got the propylene glycol here today, got enough for about 5 tubes, so ill do a fill on my green tonight and leave it sit for a week or so.

Filled green, what an incredibly messy job that can get to be.
I filled through the front til it was very close, put the C-Element in place, so far clean and zero stray glycol...
Flipped tube over and started filling the rest through screw hole, 3ml at a time, had to keep putting screw back in and moving tube to get air to the hole, finally got there and left a very small air bubble. Cant be seen anywhere in the housing with tube at operating angle, only about 3mm bubble.
Next question....
How important is the black paint on the tube bell? In cleaning the glycol off the tube, a bit of that paint came off with it. This is on the simulation green tube.

The paint is to prevent the aluminum from corroding. And it will corrode very heavily if it is exposed to the (monoetylene)glycol.
But since you used propyleneglycol, could be that nothing will happen.
Why do you ask after filling? I would leave it as is now and give it a try.

Because its on the tube bell, the graphite paint, there is no paint inside the Barco housings. The glycol had to be washed from the tube bell and this took some of that graphite paint off.
Nothing to do with internals of the housing, its all on the tube.

Yes that paint is conducting and leads static charge away. If most is still there I would not worry. I removed a sticker from the bell and took some paint off but had no problems yet.

As I understand the corrosion comes from the water that is in the solution and in this mixture the water does not vaporise or dry so that makes it corrode on and on. Both propy and ethy are coroding in my opinion because both have water and bot do not dry.

One more remark on the iceclear stuff. Did some research on it but it is just the propylene version. I remember Mike saying this was very clear stuff making me doubt too but when I asked him private he said he removed it for some reason. Just saying. In public he says something different because he can't say he was wrong ever.

Im not using ice clear, just regular clear propylene glycol.
Not sure why the question of housing corrosion came into it, im clearly refering to the graphite paint that is applied to the tube bell. The bell is outside the chamber, and is not in contact with glycol during normal operation.

The part that has come off is where the metal bracket contacts the tube bell. I am measurin 18Ohm close to the metal between paint and metal and 25 Ohm half way and 75Ohm on the edge. I think you could check that. |

Ok after 31 hours with the propylene glycol in the green it seems to do the job perfectly well. Sharp focus corner to corner, and crystal clear bright image.

So Casey did you use the propylene glycol straight or did you mix it with anything else? Would you know if its anymore corrosive than the standard stuff. |

Straight mate yeah, this is food safe Carlton United Brewry stuff, there is bare aluminum and copper inside those Lancer glycol chillers, never saw one corrode in about 17 years of working with them, so im going to assume its safe.
